I have a 2000 express chevy van. The battery died and i jump

Customer Question

i have a 2000 express chevy van. The battery died and i jump started it - no problem. When I got home I let it run for a few minutes and then shut it off and tried to restart it but it just clicked - no start - low battery. OK - need new battery. REAL problem is the alarm. The button on the dash (which usually blinks slowly when the engine is off and not at all when the engine is running) is now flashing rapidly and i forget how or the combination of steps to get it back to the slow blink mode. Please help - Thank you. Jeannie (I used you about three years ago when the shop replaced my engine and my running lights didn't work. They cut the wires and forgot to reconnect them. You sent me a wiring diagram, told me what to do and every worked out fine, thanks to you!!!)

Attempt to start the engine, then release the key to ON, vehicle will not start.Observe the SECURITY light. After approximately 10 minutes , the security light will turn OFF. The vehicle is now ready to relearn the Pass lock Sensor Data Code and/or password ***** the next ignition switch transition from OFF to CRANK. Turn OFF the ignition, and wait 5 seconds. Start the engine, the vehicle has now learned the voltage reading coming back from the ignition switch.

security light doesn.t stay on only the battery and seat belt lights on the left side of the panel stay on but the alarm is nice and loud. don't forget when i got home from the battery being jumped i tried to start the van and just got click,click,click. Should I charge the battery first? Also, the alarm system has locked the engine from stsrting.

Maybe I should disconnect the battery - charge it - then reconnect it to give the system a brand new start???
